This morning we were made aware of a security flaw within the Timthumb image resizing script, which is utilized in our themes for dynamic image resizing. It is also widely used in other WordPress themes and plugins.

As a result of this security flaw, the author of TimThumb and the author of WordThumb have worked together to release TimThumb v2 which fixes these security issues.

We’d highly recommend that you update your WooFramework like described below.

Today, the White House has released four of the modules it has developed back into the open source community. The first two are to improve scalability: Context HTTP Headers improves server efficiency, while Akamai as the name suggests integrates Drupal with Akamai's global cache network. Next, and probably of less use, is GovDelivery, which replaces Drupal's SMTP back-end and integrates with the internal governmental email system. The last module (and the most useful for the world at large) is Node Embed. As the name suggests, it lets you nest Drupal nodes inside other nodes -- Slideshows within Articles, an Author bio embedded within a blog post, and so on.

But what many users don’t know is that the wp-config.php file may be used to specify a wide variety of configurational settings, enabling you to improve the functionality, performance, and security of your WordPress-powered site.

This guide covers everything in the WordPress Codex, as well some additional tricks that you probably haven’t seen before. If you know of any other WordPress configuration tricks, share them in the comments and I will add them to the post.
